Relation between xylem and phloem increment in Silver fir (Abies alba Mill.) [PDF]

, 2017
Pri 10 zdravih jelkah (Abies alba) smo raziskali anatomsko zgradbo floemskih branik (FB) glede na njihovo širino, razmerje med številom slojev celic v FB in v ksilemskih branikah (KB) iste sezone, razlike v številu slojev celic v FBin KB po obodu ...

Tracing Oxygen and Hydrogen Isotope Signals From Water Sources to Tree‐Ring Compounds

Plant, Cell &Environment, Volume 48, Issue 8, Page 6235-6250, August 2025.
ABSTRACT Stable oxygen (δ18O) and hydrogen (δ2H) isotope compositions of tree‐ring compounds preserve information about environmental waters; however, our understanding of their isotopic relationships is hampered by the lack of long‐term data sets.

Decreasing Stem Growth in Common European Tree Species Despite Earlier Growth Onset

Global Change Biology, Volume 31, Issue 7, July 2025.
Our findings reveal that elevated winter and spring temperatures led to earlier attainment of annual growth levels, indicating an earlier onset of tree growth driven by early season warming. Despite this advancement, the earlier start did not result in increased annual growth. On the contrary, total annual growth significantly declined in three species—

The Presence of Alternative Tree Species in European Beech Forests Drives Change in Functional Diversity and Composition of Forest Floor Plant Communities

Journal of Vegetation Science, Volume 36, Issue 4, July/August 2025.
Admixing alternative tree species in European beech forests is associated with changes in the functional diversity and composition of forest floor vegetation. Higher functional richness and divergence were observed in stands containing Douglas fir, silver fir, or sessile oak, while shifts in trait composition varied depending on tree species and site ...

Comparative analysis of allozyme polymorphism of Abies alba Mill. maternal trees and their progeny in the Ukrainian Carpathians

Інтродукція Рослин, 2004
Variation of isoenzymes in two enzyme systems encoded by five loci was studied in maternal plants, seed embryos and pool of paternal garnets of the Abies alba Mill, population in the Ukrainian Carpathians.

Seasonal dynamics of xyogenesis and phloiemogenesis in silver fir (Abies alba Mill.) [PDF]

, 2017
Preučili smo dinamiko nastajanja ksilemskega in floemskega letnega prirastnegaplašča oz. branike pri navadni jelki (Abies alba) v rastni sezoni 2003. Vzorce floema, kambija in ksilema smo vsak teden vzeli iz dveh navideznozdravih odraslih jelk. Raziskave

Drought influence over radial growth of Mexican conifers inhabiting mesic and xeric sites [PDF]

, 2017
Drought is a major constraint of forest productivity and tree growth across diverse habitat types. In this study, we investigated the drought responses of four conifer species growing within two locations of differing elevation and climatic conditions in

Dynamic Shifts in Radial Sap Flow of Two Temperate Tree Species in Response to the Dry Summer 2022

Ecohydrology, Volume 18, Issue 4, June 2025.
ABSTRACT Species‐specific regulation of water fluxes and storage in the xylem are important drivers of drought tolerance. However, differences may occur along the radial profile of the xylem, potentially modifying drought responses. We investigated sap flow (Js) and stem water content (WCstem) at two xylem depths, and diurnal stem radius variations of ...

The mid-Holocene extinction of silver fir ( Abies alba ) in the Southern Alps: a consequence of forest fires? Palaeobotanical records and forest simulations [PDF]

, 2018
Pollen records suggest that Abies alba played a dominating role in both the montane and lowland forests at the border of the Southern Alps between ca. 8500 and 5700 years ago. Two major declines in fir, at about 7300-7000 cal b.p. and at ca. 6000 cal b.p.
